The # assert fails because we have unlocked the PTE in text_area_cpu_up_mm(). # # Instead leave the PTE locked and only unlock it when we tear down the # patching_mm for the CPU. That avoids the assert failing, and nothing # else should be using the PTE so leaving it locked is arguably more # correct. # # Fixes: c28c15b6d28a ("powerpc/code-patching: Use temporary mm for Radix MMU") # Reported-by: Nathan Chancellor <nathan@kernel.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 1562551aec8bb15974c69ee79b8da8cc688e7340 # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc85xx_defconfig # Added to kconfig CONFIG_PPC_E500MC=y # Added to kconfig CONFIG_VIRTUALIZATION=y # Added to kconfig CONFIG_KVM_E500MC=y # Added to kconfig # < make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig .config:4449:warning: override: reassigning to symbol PPC_E500MC .config:4450:warning: override: reassigning to symbol VIRTUALIZATION # make -s -j 160 ARCH=powerpc O=/kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- In file included from /kisskb/src/include/linux/build_bug.h:5, from /kisskb/src/include/linux/container_of.h:5, from /kisskb/src/include/linux/list.h:5, from /kisskb/src/include/linux/module.h:12, from /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:15: /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c: In function 'allocate_bd': /kisskb/src/include/linux/err.h:22:49: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] 22 \| #define IS_ERR_VALUE(x) unlikely((unsigned long)(void *)(x) >= (unsigned long)-MAX_ERRNO) \| ^ /kisskb/src/include/linux/compiler.h:78:45: note: in definition of macro 'unlikely' 78 \| # define unlikely(x) __builtin_expect(!!(x), 0) \| ^ /kisskb/src/drivers/net/ethernet/freescale/fs_enet/mac-scc.c:139:13: note: in expansion of macro 'IS_ERR_VALUE' 139 \| if (IS_ERR_VALUE(fep->ring_mem_addr)) \| ^~~~~~~~~~~~ /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:341.15-350.5: Warning (pci_device_reg): /pci@e0008000/i8259@19000: PCI unit address format error, expected "12,0" /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:341.15-350.5: Warning (pci_device_reg): /pci@e0008000/i8259@19000: PCI unit address format error, expected "12,0" /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) Completed OK # rm -rf /kisskb/build/powerpc-next_mpc85xx_defconfig+KVM_powerpc-gcc11 # Build took: 0:03:31.491447
